Apparatus and Methods for the self-alignment of separated regions in a lateral MOSFET of an integrate circuit. In one embodiment, a method comprising, forming a relatively thin dielectric layer on a surface of a substrate. Forming a first region of relatively thick material having a predetermined...
Requirements for tunneling 6. pn Junction Diode Requirements for tunneling (1) Must be filled states on one site of the barrier and empty states on the other side of the barrier at the same energy (2) Width of the potential energy barrier : very thin < 100 Å ※ Zener process Tunneling...

The ability of the PN junction to conduct significant current only in the forward-biased direction allows it to function in electric circuits much like a check valve functions in mechanical circuits. A generic PN junction and the diode circuit symbol are shown inFigure 5.Notice that the triangle...

Tags Circuit Current electricity Current flow Diode Pn junction In summary, the PN junction inside a diode allows electrical current to flow in one direction and not in the opposite direction. This is due to the properties of the P-type and N-type materials, where the P-type material has ...

region 2 and in thickness sufficiently thicker than the region 3, breakdown starting voltage is set at a high value while internal resistance can be inhibited at a low value by the thickness of the region 2 because carrier concentration in the region 2 near a P-N junction surface is lowered...
pn junction diode. If you have done upto this, the forward bias circuit of pn junction diode is complete. Now all we need to do is understand how the pn junction diode behaves when we increase the voltage levels from 0 to say 10 volts or 100 volts. We have learned that if we apply...
